I think you can simulate hands by doing tracelines. So rock-climbing would be possible. And boxing probably too ... because tracelines would map to bones of real hands.

I wondered whether I can achieve doing something like combat in Dark Messiah Of Might And Magic http://www.youtube.com/watch?v=caB1jodPQPQ with tracelines. Quake axe is done just by one traceline.

First, I have to say that when I did try out your code, I was very impressed. Contrary to my expectations, it worked quite well and seemed fairly consistent. The FL_ONGROUND and grab-key suggestions came from actually trying things.

I couldn't see your pics (1x1 gifs), but I think I know to what problem you are referring: very thin ledges: quite right. I hadn't thought of that. While your idea of shooting up from the lower position (collision point) sounds good, it won't work in quake as the engine never blocks a trace going from solid to non-solid (it doesn't even get "all solid" right all the time).

However, obtaining the (lower) collision point, going half a quake unit beyond it, and doing a traceline from the upper point (same distance as the collision point plus a bit) should work: anything smaller than 1 quake unit is either a wedge or normally impossible.

[edit]I just realized that climbing slopes might be interesting. but making good use of the plane information returned from traceline might help.

I'll see if I can get some hacking done this weekend.
